Electronic device with chip module

Abstract

An electronic device includes a motherboard and a chip module. The motherboard includes a first connector. The chip module includes a circuit board parallel to the motherboard, a chip mounted on the circuit board, a second connector, and a fastener. The second connector of the chip module is electronically connected to the first connector of the motherboard. The fastener extends through the circuit board, to fix the chip module compactly and firmly in place.

What is claimed is: 
     
         1 . A chip module connected to a motherboard having a first connector, comprising:
 a circuit board;   a chip mounted on a first surface of the circuit board; and   a second connector mounted on a second surface of the circuit board opposite to the first surface, to be connected to the first connector of the motherboard.   
     
     
         2 . The chip module of  claim 1 , further comprising a fastener extended through the circuit board, to fasten the circuit board to the motherboard. 
     
     
         3 . The chip module of  claim 1 , further comprising a positioning pole connected between the motherboard and the circuit board. 
     
     
         4 . The chip module of  claim 3 , wherein the circuit board defines a through hole, the positioning pole defines a screw hole aligning with the through hole, a fastener extends through the through hole of the circuit board, to be screwed in the screw hole of the positioning pole. 
     
     
         5 . The chip module of  claim 3 , wherein the positioning pole comprises two resilient hooks extending down from the positioning pole, to be latched to the motherboard. 
     
     
         6 . An electronic device, comprising:
 a motherboard comprising a first connector; and   a chip module comprising a circuit board parallel to the motherboard, a chip mounted on a first surface of the circuit board, a second connector mounted on a second surface of the circuit board opposite to the first surface, and a fastener; wherein the second connector of the chip module is electronically connected to the first connector of the motherboard, and the fastener extends through the circuit board, to be fixed to the motherboard.   
     
     
         7 . The electronic device of  claim 6 , wherein the chip module further comprises a positioning pole connected between the motherboard and the circuit board. 
     
     
         8 . The electronic device of  claim 7 , wherein the circuit board defines a through hole, the positioning pole defines a screw hole aligning with the through hole, the fastener extends through the through hole, to be screwed into the screw hole of the positioning pole. 
     
     
         9 . The electronic device of  claim 7 , wherein the motherboard defines a latching hole, the positioning pole comprises a latching portion latched in the latching hole. 
     
     
         10 . The electronic device of  claim 9 , wherein the positioning pole comprises two resilient hooks extending down from a bottom of the positioning pole, the hooks extend through the latching hole, to be abutted against a bottom surface of the motherboard.
